The inimitable properties of nano silver make them interesting for commercial and scientific devices such as an antimicrobial, antiseptic, biosensor materials, composite fibers, materials frozen superconductors, cosmetic products and electronic components.
Various physical and chemical methods are used to synthesize and stabilize nano silver [1, 2]. Highly accepted chemical approaches have been used to synthesize silver nanoparticles including chemical reduction, the use of a variety of inorganic and organic reducing agents, chemical and physical reduction, electrochemical and electrolytic engineering. .
Recently, nanoparticle synthesis is a leading scientific field of interest and is gaining increasing attention for providing environmentally friendly (green chemistry) nanoparticle mining.
Green chemistry approaches including mixed valence polyoxometalates, Tollens, polysaccharides, irradiation and biological methods have advantages over conventional methods involving chemical agents involved. environmental toxicity.
The antibacterial properties of nano silver show medical relevance for clinical research and applications and are essential for human beings in everyday life [3]. Silver nanoparticles replace weak antimicrobial agents involved in water disinfection, textiles, medical and food packaging, and more.
They may also participate in the neutralization of these binders, thereby preventing the formation of biofilms [4]. Irradiation and biological methods have advantages over conventional methods involving chemical agents involved in environmental toxicity.

Currently, nano chemistry has become a development direction of Nanoscience [5]. Nanometer-sized metal particles show a comparison of unique physical, chemical and biological properties and vary significantly with their macroscopic counterpart based on a high surface-to-volume ratio. of them.
These nanoparticles exhibit size and shape dependent properties such as catalysts and perceptibility to optics, antimicrobial activity, and data storage [6-9].
For example, the antimicrobial activity of metal nanoparticles is diverse, including colloidal silver that is closely related to their size; that is, the smaller the silver nuclei, the greater the antimicrobial activity. Moreover, the catalytic activity of these nanoparticles also depends on size as well as structure, shape, size distribution and physical and chemical environment.
To correct irregular size distributions, specific management of appearance, size and size distribution is carried out using various synthesis, reducing agent and stabilizer strategies [10-12 ]. The optical properties of metal-bearing nanoparticles are mainly based on its surface plasmon resonance, where the plasmon is a collective oscillation of free electrons inside the metal-bearing nanoparticles.
It is known that the Plasmon resonance peaks and line widths are sensitive to the nanoparticle size and shape, metallic form, and surroundings. For example, nano clusters consisting of 2-8 silver atoms may be the best alternative to storing optical knowledge. Furthermore, fluorescence emissions across clusters can be exploited at bio-labels and electroluminescent screens [13-14].
Recently, nano silver has become interesting for cancer treatment applications such as metastatic tumor agent, in diagnosis and investigation, so the review explores the mechanism of action of metastatic tumors. , treatments and limitations of nanoparticles in cancer medical support.
Silver nanoparticles are also effective against certain broad-spectrum gram-negative and gram-positive bacteria, along with some antibiotic resistant strains [15]. Gram-negative bacterial clusters, for which the bactericidal activity of silver nanoparticles has been confirmed, include:

The efficacy of silver nanoparticles was also reported against gram-positive bacteria: Bacillus [20], Enterococcus [21], Listeria [22], Staphylococcus [23] and Streptococcus [24].
Recent studies have shown that the use of silver nanoparticles in combination with several antibiotics such as penicillin G, amoxicillin, erythromycin, clindamycin and vancomycin, produces a synthetic effect against E. coli and S. aureus. [25]. Some studies have also shown that silver nanoparticles can also be an effective weapon against viruses [26] thereby inhibiting their replication.
Their activity has been confirmed even against HIV-1 viruses [27] and influenza viruses [28]. The effectiveness of the processes leading to virus destruction depends closely on the shape and size of the nanoparticles [27].
Silver nanoparticles are effective and fast acting agent for killing various fungi such as Aspergillus [29], Candida [30] and S accharomyces [15].

Furthermore, we explore applications of silver nanoparticles in all respective fields and mechanical aspects of silver nanoparticles as an antimicrobial agent.
The applications of AgNP in different fields
Nano silver is widely applied as antimicrobial agents for food preservation, medical, textile coatings and a wide variety of environmental applications.
Products prepared by or from AgNPs have been approved by a range of accredited bodies, including the US FDA, US EPA, SIAA of Japan, the Korea Institute for Research and Testing for Industrial Chemistry. substances and FITI Institute for Research and Testing [31-36].
As anti-microbial agents, AgNPs are performed in a variety of applications related to the disinfection of medical devices, home appliances and water treatment [37-38]. Furthermore, this has inspired the textile industry to use AgNPs in many textiles.
